We won't find a perfect system to account for everything, but we can define how to calculate the rating for specific tournaments, and instead of aging, it's better to come up with or use something similar to the suggestion from forum user "natasha":
for example, each player starts with an initial capital of, say, 1000 rating points, and it changes depending on their performance in tournaments. The stronger the players you beat, the more points you gain, and they lose... this way, we can also solve the issue of annual resetting.
Even someone who joined in June can beat the leader a couple of times and score more than they did in a whole year!!!:smile49:
